Multiband signal acquisition using improved modulated wideband converter
The Journal of Engineering, 2019 In this study, the authors stress the problem of sampling and recovering sparse wideband signals. A new methodology for sparse multiband signal acquisition using sinusoidal frequency modulation (SMF) multiplier-based modulated wideband converter (MWC) is

Sub-Nyquist processing with the modulated wideband converter [PDF]
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010 Sub-Nyquist systems capture the signal information in a different fashion than uniform high-rate samples. Consequently, digital processing, which is the prime reason for leaving the analog domain, becomes challenging. We propose a digital algorithm that translates samples obtained by the modulated wideband converter, a recent sub-Nyquist system, to the

Expected RIP: Conditioning of The modulated wideband converter [PDF]
2009 IEEE Information Theory Workshop, 2009 The sensing matrix of a compressive system impacts the stability of the associated sparse recovery problem. In this paper, we study the sensing matrix of the modulated wideband converter, a recently proposed system for sub-Nyquist sampling of analog sparse signals.

Wideband spectrum sensing based on advanced sub-Nyquist sampling structure
EURASIP Journal on Advances in Signal Processing, 2022 As the bandwidth increases, the high-speed sampling rate becomes the bottleneck for the development of wideband spectrum sensing. Wideband spectrum sensing with sub-Nyquist sampling attracts more attention and modulated wideband converter (MWC) is an ...
